Abstract
This study was conducted to evaluate the effect of mulching material and planting density on growth and bulb development of shallot. The transparent PE film was better than black PE film as a mulching material for the overwintering shallot crop. Transparent PE film mulching promoted plant growth and increased marketable yield by 21% as compared with that of the black PE film-mulched crop. However, the bulb size was not significantly affected by the type of mulching film. The height and width of ridge and planting density significantly affected the growth and bulb yield of the moisture sensitive shallot. Bulb yield of the shallot planted in five rows in 120 cm wide ridges (20,833 plants per 10 a) was 1,332 kg per 10 a, which was 1.7 times as high as that by the crop grown in three rows in 120 cm wide ridges (12,500 plants per 10 a). In conclusion, the shallot crop is recommended to be cultivated in five rows in 120 cm ridges mulched with the transparent PE film.
